Clark County, Nevada
Recorded hazard history: storm events since 1950, federal disaster declarations since 1953, flood insurance claims since 1978, and FEMA's risk index.
NCEI notes that Storm Data is compiled from a variety of sources including the National Weather Service, other federal, state and local agencies, the media and the public; that property and crop damage figures are estimates; and that some events are recorded by NWS forecast zone rather than by county. FEMA notes that NFIP claim records are redacted and aggregated to protect the privacy of policyholders. NCEI storm records through 30 Jun 2026; OpenFEMA declarations refreshed 1 Oct 2026; NFIP claims as of 8 Sep 2026.
The NCEI record lists 937 events for Clark County, Nevada, between 1950 and 2026; floods and flash floods account for the largest share.
That is 11.9 events per 100 square miles, above the Nevada figure of 8.0, and 4.1 per 10,000 residents against 27.9 statewide.
32 events fall in the 12 months to 30 Jun 2026. NCEI attributes 27 deaths and 204 injuries to events in the county, with property damage estimated at $298M.
FEMA has designated the county in 14 federal disaster declarations since 1953; the most recent is Covid-19 Pandemic (major disaster, 4 Apr 2020).
National Flood Insurance Program policyholders in the county filed 626 claims since 1978, of which 368 were paid, totalling $9.3M (about $25K per paid claim). FEMA counts 1,197 residential flood policies in force.
FEMA's National Risk Index rates the county's overall risk as "Very High" and its expected annual loss as "Relatively High" ($813M a year across 18 hazards).

Events by decade
Trend: 668 events in the 20 years to 2025 against 211 in the 20 years before. Reporting practice changed in 1996 and again with automated reports in the 2000s, so decade totals measure the record as much as the weather.
Events by type
Hazard pages exist for hail, tornado, flood, wind and winter where the county has at least 10 recorded events. "Other" covers heavy rain, debris flow, dust, funnel clouds and similar reports.
